how to call method in controller from a UIButton in a UITableViewCell - ios

Question

I have a UITableView with my own UITableViewCells, which contains a UIButton. The UITableView is added to my ViewController at runtime. Everything works fine that way that I see the Button in the Cells. When pressing the Button my action is called in my UITableViewCell.
Now. How can I call a method in my ViewController, when the button is pressed in my cell ?
In my UITableViewCell Class I have a button in a cell:
let framebutton_in_cell:CGRect=CGRectMake(0, 0, 40,40);
button_in_cell.frame=framebutton_in_cell;
button_in_cell.addTarget(self, action: "buttonActionText:", forControlEvents: UIControlEvents.TouchUpInside)
button_in_cell.tag = 1;
var image2 = UIImage(named: "book");
button_in_cell.setImage(image2, forState: .Normal)
var transparent2:UIColor=UIColor(red: 0, green: 0, blue: 0, alpha: 0.0);
contentView.addSubview(button_in_cell);
and I have my function buttonActionText:
func buttonActionTimeline(sender:UIButton!)
{
var btnsendtag:UIButton = sender
//do something
}
My UITableView is added at runtime to my UIViewController:
override func viewDidLoad() {
super.viewDidLoad()
let fSearchResultY:CGFloat=fButtonHeight+fButtonY;
searchResults.frame = CGRectMake(0, fSearchResultY, screenwidth, screenheight-fSearchResultY);
searchResults.delegate = self;
searchResults.dataSource = self;
searchResults.registerClass(CellResult.self, forCellReuseIdentifier: "Cell");
self.view.addSubview(searchResults);
Now I would like to call a method in my Viewcontroller insteed of a method in my UITableViewCell. How can I achieve this ?

Answer 1

Just don't add target from UITableViewCell class instead add it in cellForRowAtIndexPath method
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cellIdentifier", forIndexPath: indexPath) as! SomeCustomCell
cell.button_in_cell.addTarget(self, action: "viewControllerMethod:", forControlEvents: UIControlEvents.TouchUpInside)
}

Answer 2

A very simple solution :-
Just declare delegate method in your Custom cell.
Set the delegate of Cell with the View Controller cell.delegate=self;
Now call the delegate method on Cell's button action and also send the button.tag as object(if needed) , it will directly call your View Controller's delegate method which is defined .

I didn't got your question properly ?Is this u r looking for
func buttonActionText(sender:AnyObject){
CGPoint buttonPosition=sender.convertPoint(CGPointZero, fromView: self.tableView)
NSIndexPath indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];
}

Create a subclass of UITableviewCell. In my code i have used Question Cell
func buttonActionTimeline(sender: UIButton!)
{
var btn:UIButton=sender as UIButton
let point = tblVIew.convertPoint(CGPointZero, fromView: sender)
let indexPath : NSIndexPath = tblVIew.indexPathForRowAtPoint(point)!
let cell = tblVIew.cellForRowAtIndexPath(indexPath) as QuestionCell // Your custom cell class name
cell.loaddata() // add this method in to custom cell class
}
